I installed two 12" Perma-Cool fans in front of the radiator as pushers. This allowed me to keep my radiator in the factory position
instead of cutting up the front core and locating the radiator down and inside it.
These two fans in combination with the 2 core aluminum radiator do a very good job of cooling the truck. I have not the slightest
hint of over heating or even coming close to it.
This is easiest to do with the radiator and A/C condenser removed.
I installed the bolts from the engine bay side and then tack welded them from the inside. So now they are essentially just studs sticking out.
This will allow me to remove a fan in the future without having to pull the radiator and A/C condenser.
Here are the fans installed.
From the engine bay side.
Radiator and A/C condenser re-installed.
Grill installed. I've since installed a billet grill which hides the fans very nicely.
